The invention relates to closet seat hinges.

An object of the invention is to provide a.

-' simple but elfective'closet seat hinge inolu d-' 'ing a pair of hinge members which are securely and rigidly attached to opposite side edges of the seat member to prevent weaving of the parts and to permit expeditious further tightening in the event of shrinkage of the seat member. I

Another object of theinvention is to provide an adjustable friction between the parts bywhich the cover may be made to remain at any desired angle without falling, thus avoiding slamming of the cover and also permitting thecover to stand at an angle less than 90 from its horizontal position in cases where the flush tank extends over the closet bowl more than the usual distance. i i

A further object ofthe invention is to provide the hinge with s'elf contained stop means which will limit the rearward movement of the cover. V Y i A further object ofthe invention is to construct the hinge in a manner which will permitconvenient assembly of the parts and facilitate cleaning. i

The inventionifurther consists in theseveral features hereinafter set forth and more particularly defined by the annexed claims.

Fig. 1 is a detail sectional View, similar to Fig. 3, of a closet seat assembly including a modified form ofcover mounting;

Fig. 5 is a fragmentary sectional elevation of the closet seat assembly of Fig. 4, taken generally alo'ngthe line 55 of Fig. 4, and i Fig. 6 is a fragmentary detail view of one of the hinge posts or. standards.-

In these drawings, the numeral 10 desig-' nates 'a closfet bowl having apertures at its rearlportions receiving therein a pair of spaced upstanding posts or standards 11 seou'redin place by nuts '12, the usual rubber washers 13 being provided. The upper ballshaped ends of the posts Or standards are provided with laterally opening bores having journaled therein the opposite ends of a hori-' zontal shaft or pin 14 which extends fixedly through the rear portion of a seat member 15.

In that form of the invention shown in Figs. lfto3, a cover 16 is arranged abovethe seat 15 and each has a narrowed rear portion presenting parallel side cheeks. A pair of angular hinge plates 17 have their lower portions disposed between the opposite side cheeks of the seat 15 and theadjacent posts 11, and are apertured to pivotally surround the shaft 14, there being washers 18 interposed between the hinge plates and the cheeks of the seat. The upper portions of the hinge plates bear against the side cheeks of the coverand are each providedwith a pair of spaced lugs 19, which enterand closely fit withinbores 20formed in the cover. Abore 21 is formed in each hinge plate betweenthe lugs 19 and registers with a horizontal bore 22 of the same diameter formed through the rear portions of the cover-between its opposite side cheeks. A

rod 23 of smaller diameter than the bore 22 extends longitudinally within the bore and has its opposite ends screwed into internally threadedbushings 24twhich fit closely within thebores 21 in the hinge plates and in the opposite ends ofthe registering box-e22 in the cover. The outer ends of the bushings 24 are provided with polygonal heads 25 which'engage the outer facesof the hinge plates for clamping the hinge plates into firm'engage- 'ment with the side cheeks ofthe cover,'thus avoiding loosening of the hinge plates and wabbling or weaving of the cover.

In that formof the invention shown in Figs; 4 and 5, angular hinge plates 17 similar to the hinge plates 17, are apertured to receive a pair of parallel rods 23 passing through bores 22' in the rear portion of a cover 16. Each rod is headedat one end and atits other end is adjustably screwed into an internally threaded bushing 24 which fits 'closelv within one of a pair of bores 21' in one'of the hinge plates, the bushingbeing pro-' vidediwith a slotted head 25'. By turning the bushings 24: the hinge plates areadjustably clamped into firm engagement with the side cheeks of the cover.

The hinge plates 17 and 17 are each provided at their rear portions with lugs 26, which are adapted to engage sloping stop abutments or shoulders 27 on the "hinge posts 11 for limiting the rearward movement of the hinge plates and the attached cover, as seen in Fig. 5, the cover in its rearward position being approximately vertical. By this means the cover is limited in its rearward movement without requiring its engagement with the flush tank, thus avoiding. knocking of the cover against the tank and possible ma-rring of the finished surfaces of the parts.

If the material of the cover should shrink for any reason the bushings 24 can be readily turned to restorethe clamping engagement.

cover but also re-enforces the cover.

I The rod 23 not only serves to clamp the hinge plates against the opposite side faces of the between the hinge plates and the side cheeks 15 of the seat extension, and this adjustable friction is relied on to retain the cover in any angular position without danger of slamming. The life of the hinge is thus lengthened and the cover is permittedto stand at an angle less than 90 from its horizontal position.

V the cover.

The latter feature is desirable when the flush tank extends over the bowl more than the usual distance, which would prevent the cover from traveling to its vertical position.

Since the seat and cover are both pivotally mounted to swing about the same axis the raising. or lowering of the seat while the cover is in lifted position will not cause movement of Except for the cover stop feature, the parts of'the' hinge maybe reversed, that is, those parts that are connected with the seat may be connected with the cover, and those parts that are connected with the cover may be connected with the seat. The terms seat and cover are, therefore, interchangeable as used in the claims in preference to designating them generically as members. i

lVhat I claim as new and desire to-secure by Letters Patent is:

1. The combination, with a closet seat and a cover thereabove, of a pair of standards adapted to be secured to 'a closet bowl, a hinge pin extending between and mounted in said standards and passing through the rear portion of said closet seat, a pair of hinge plates having their lower portions pivoted on said pin and engageable with opposite side edges of the rear portion of said cover, and means passing through said cover for fixedly clamping said hingeplates to said cover.
